SUMMERTIME
DECISIONS
It's officially summer,
new releases are out and
it's time to plan for next year.
Breeders showcased some
big genetic improvements
in annuals, perennials and
foliage options at the 2024
California Spring Trials.
Heat and drought tolerance
have become a big part of
the " behind-the-scenes "
genetics. Taking center stage
are bright colors and more
manageable growth habits
for small space applications.
Start your search on page 16
for new 2025 varieties.
Bailey Nurseries has
also been busy making
improvements in the smooth
hydrangea category. Years of research and trialing have produced a
grower-friendly, compact and easier to finish new release. Get all the
details on page 35.

CEA R&D
How efficiently plants use light energy can vary depending on other
environmental conditions like temperature and humidity. On page 6,
read how researchers in CEA at University of Georgia (UGA) are using a
plant biofeedback system to help develop better lighting strategies.
And don't miss best practices in managing vapor pressures in the
greenhouse and tips for improved ventilation throughout plant canopies
on page 28.
If you have been battling with blooming through the spring season,
check out page 58 for some troubleshooting tips. Erik Runkle, professor
and floriculture specialist at Michigan State
University, discusses some of the reasons growers
could be experiencing late flowering.
